Title: Method for deicing energized electrical transmission lines
Inventor: BROCHU JACQUES
IPC: H02G7/16
Filed: 2003-10-01
Abstract: The invention concerns a method for deicing energized electrical transmission lines by means of an apparatus capable of producing an angular offset between its terminals. The method consists in: selecting segments (4, 6) of electrical transmission lines to de deiced, connecting the segments (4, 6) so as to form a loop, connecting the apparatus in series with the segments (4, 6) of the loop to be deiced. In the case of an apparatus with adjustable angular offset, it consists in switching on the apparatus and adjusting the angular offset to impose an increase of current flowing in at least one of the segments (4, 6) as the case may be. In the case of a apparatus with fixed angular offset, it consists in using a switch (54) or a circuit breaker (28) so as to connect the apparatus in the loop, the apparatus and the line segments being previously selected such that the angular offset imposes the required current increase to the deicing of at least one of the segments (4, 6) of the loop.

Title: Arrangement for carrying out shelling of a target by means of a rapid-firing ordnance piece
Inventor: HAGLUND INGEMAR
IPC: F41G3/04
Filed: 1990-06-27
Abstract: ABSTRACT            Shelling of a target (16) is carried out by means of a rapid-firing ordnance piece (1) with a number of shells (4, 5, 6) which can be fired successively one after the other. The ordnance piece is connected to or comprises an arrangement with manoeuvring/computer equipment (17) which receives incoming data (19) and control commands (20).  As  a  function  of  the  input  information,  the equipment  (17)  supplies  control  information  to  the ordnance piece and the ammunition units. This control information   constitutes   adjustment   or   selection information which  allocates  to  the  ammunition units different flight times between the ordnance piece and the target, so that they reach the target (16) at essentially the same point in time after the launch from the ordnance piece,  in spite of the fact that the launch of the ammunition units takes place at different points in time.            It  is  proposed  that  Figure  1  should  accompany  the abstract.

Abstract: ABSTRACT           An  apparatus  for  compacting  compressible waste  such  as  cardboard,   cartons,   wood  refuse, domestic garbage or the like should be designed in such a way that the garbage is reliably conveyed at specific uniform intervals into a receiving container or the like and that during the conveying process odour  problems  due  to  the  conveyed  waste  cannot occur.    According to the invention,  this  is made possible by providing a rotatably driven cylindrical drum  which  is  mounted  in  a  housing  having  a substantially vertical material feed and a material discharge channel and having a chute of square or rectangular cross-section,   symmetrical to the drum, which penetrates into the drum from its casing and which  serves  to mount  a  cross-sectionally  fitting compacting   piston,    which   has   two   partially cylindrical surfaces, opposite one another, the radii of which correspond to the radius of the drum and the distance  between  the  cylindrical  surfaces  being smaller  than  the  diameter  of  the drum,   two flat surfaces which are opposite  one another are provided between the surfaces,  the distance between the two flat  surfaces  being  likewise  smaller  than  the diameter of the drum wherein the compacting piston has,  in a plane which is vertical to the axis of the drum,  an elongated hole like guide which is inclined with  respect  to  the  chute  and of  which  the  ends point,   in the direction of rotation of the drum, toward  the  trailing  connecting  edges  between  the partially cylindrical and the flat surfaces of the drum,  wherein a fixed pivot engages the guide,  the axis of the guide being in the vertical median plane through   the   drum   and   the   exterior   diameter corresponds to the distance between the two straight surfaces of the guide, wherein the pivot is offset in downward direction below the horizontal median plane through the drum,  and is thereby directed toward the discharge channel.

Abstract: A method of producing laminated veneer lumber (LVL) with good dimensional stability, characterized by a particular lay-up of the veneers and the veneers being of at least two different wood species.  The particular veneer lay-up and species arrangement, minimizes the tendency of warping and cracking of the LVL.  All veneers are laid-up in pairs by species with the loose sides of each pair contacting each other and with the species pair sequence from face to core being identical on either side of the center ply or center line.  The veneer tight faces of different species are bonded to one another.  The dimensional stability of the LVL is optionally enhanced by a water repellent, flow promoter and bulking agent that is incorporated into the adhesive before application onto the veneer.  The different species veneers are dried to different moisture contents before lay-up with the denser species being of lower moisture content than the less dense species.

Title: Process and apparatus for packing bulk materials
Inventor: FOCKE HEINZ
IPC: B65B9/10
Filed: 1991-06-28
Abstract: A b s t r a c t : (referring to Fig. 1) When tube bags (10) and similar  packages  are  manufactured and  filled with bulk material of awkward shapes, especially with  potato  crisps,  the  filling  process  is   difficult because  the  pieces to be packed get caught on one another. For this reason, the invention suggests to shake or  vibrate the  tube  bag (10) or a foil tube (14) for making this tube bag (10) at least during a phase of the filling process  and in  particular  immediately  therafter. This accelerates the filling process and above all frees  the  region  where  the closure seam  (with  bottom  seam  20)  is  applied  of any residues of the material to be packed. Shaking or  vibration effects  are  generated  by  oscillation generators (29, 30) which are preferably operating according  to  the  principle of  a loudspeaker, i.e. which set an air column oscillating. These oscillations are then transferred  to  the  foil  tube (14) and the pack contents.
